I think you missed quite a lot. Revan wore his robes during the Mandalorian wars, and his name never changed - so I would think it would be kind of obvious when a Sith Lord comes, dressed in Revan's old Mand. War robes, calling himself Darth Revan, the Exile would recognize him.
Besides, you must have missed all of those talks with Kreia.
